The Company and Basis of Presen

The Company and Basis of Presentation	6 Months Ended
	Jun. 30, 2020
Accounting Policies [Abstract]
The Company and Basis of Presentation	Note 1. The Company and Basis of Presentation SiTime Corporation (the “Company”), was incorporated in the State of Delaware in December 2003. The Company is a provider of silicon timing systems. The Company primarily supplies oscillator products that are comprised of a MEMS resonator and clock IC that is integrated into a package, as well as standalone resonators. The Company has also started to sample clock ICs. The Company’s products are designed to address a wide range of applications across a broad array of end markets. The Company operates a fabless business model and leverages its global network of distributors and resellers to address the broad set of end markets that it serves. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments of a normal, recurring nature, which are necessary to state fairly the financial information included therein. These financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in SiTime Corporation's Annual Report on Form 10-K for the fiscal year ended December 31, 2019. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The Company was a wholly-owned subsidiary of MegaChips Corporation (“MegaChips”), a fabless semiconductor company based in Japan and traded on the Tokyo Stock Exchange until the Company completed its initial public offering in November 2019. MegaChips remains the largest stockholder of the Company and held approximately 44.9% of the Company’s outstanding common stock as of June 30, 2020. Outbreak of Coronavirus Disease 2019 (“the COVID-19 pandemic”) On March 11, 2020, the World Health Organization characterized the outbreak of the coronavirus disease known as COVID-19 as a global pandemic and recommended containment and mitigation measures. On March 13, 2020, the United States declared a national emergency concerning the outbreak, and several states and municipalities have declared public health emergencies. To combat the spread of the COVID-19 pandemic, the United States and other foreign countries in which the Company operates have imposed measures such as quarantines and “shelter-in-place” orders that are restricting business operations and travel and requiring individuals to work from home (“WFH”), which has impacted all aspects of the Company’s business as well as those of the third-parties we rely upon for our manufacturing, assembly, testing, shipping and other operations. The Company anticipates the global health crisis caused by the COVID-19 pandemic will negatively impact business activity across the globe and the Company's results of operations. The inputs into the Company’s judgments and estimates consider the economic implications of the COVID-19 pandemic, as the Company knows them, on the Company’s critical and significant accounting estimates. The extent to which the COVID-19 pandemic may impact the Company’s business will depend on future developments, which are highly uncertain and as such, the Company is not able to estimate the effects of the COVID-19 outbreak on its results of operations, financial condition, or liquidity for fiscal year 2020. Reporting Calendar The Company’s fiscal year begins on January 1 of the year stated and ends on December 31 of the same year. The Company reports its results on a calendar year basis. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Significant Accounting Policies The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. There had been no changes to these accounting policies except for the recently adopted accounting guidance as discussed below. Recently Adopted Accounting Guidance In August 2018, the Financial Accounting Standard Board (“FASB”) issued Accounting Standard Update (“ASU”) 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use-software. The adoption of this standard on January 1, 2020 did not have any impact on the Company's consolidated financial position, results of operations and cash flows. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements in Topic 820. The adoption of this standard on January 1, 2020 did not have any impact on the Company's disclosures. New Accounting Pronouncements Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. The new standard will be effective for fiscal years beginning after December 15, 2020. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial position, results of operations and cash flows. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes the credit loss model from an incurred loss approach to an expected loss approach. It requires the application of a current expected credit loss (“CECL”) impairment model to financial assets measured at amortized cost (including trade accounts receivable) and certain off-balance-sheet credit exposures. Under the CECL model, lifetime expected credit losses on such financial assets are measured and recognized at each reporting date based on historical, current, and forecasted information. The standard also changes the impairment model for available-for-sale debt securities, eliminating the concept of other than temporary impairment and requiring credit losses to be recorded through an allowance for credit losses. The amount of the allowance for credit losses for available-for-sale debt securities is limited to the amount by which fair value is below amortized cost. The standard is effective for interim and annual periods beginning after December 15, 2022. A modified retrospective adoption method is required, with a cumulative-effect adjustment to the opening retained earnings balance in the period of adoption. The adoption of this standard is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows.

Income Tax Disclosure [Abstract]
Income Taxes	Note 7. Income Taxes The quarterly provision for (benefit from) income taxes is based on applying the estimated annual effective tax rate to the year to date pre-tax income (loss), plus any discrete items. The Company updates its estimate of its annual effective tax rate at the end of each quarterly period. The estimate takes into account annual forecasted income (loss) before income taxes, the geographic mix of income (loss) before income taxes and any significant permanent tax items. On March 27, 2020, the “Coronavirus Aid, Relief, and Economic Security Act” (“CARES Act”) was signed into law. The new legislation includes a number of income tax provisions applicable to individuals and businesses. Due to historical net operating losses incurred in the U.S., the CARES Act did not have material impacts on the Company’s condensed consolidated financial statements as of June 30, 2020. The Company continues to examine the elements of the CARES Act and the impact it may have on its future business. The following table presents the provision for income taxes and the effective tax rates for the three and six months ended June 30, 2020 and 2019: Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 (in thousands) Loss before income taxes $ (5,604 ) $ (5,448 ) $ (10,695 ) $ (8,318 ) Provision (benefit) for income tax 1 (1 ) (1 ) (1 ) Effective tax rate 0 % 0 % 0 % 0 % The Company’s effective tax rate may vary from the U.S. federal statutory tax rate due to the change in the mix of earnings in tax jurisdictions with different statutory rates, benefits related to tax credits and the tax impact of non-deductible expenses, existence of full valuation allowance on its deferred tax assets, and other permanent differences between income before income taxes and taxable income. A valuation allowance is established or maintained when, based on currently available information and other factors, it is more likely than not that all or a portion of the deferred tax assets will not be realized. The Company regularly assesses its valuation allowance against deferred tax assets on a jurisdiction by jurisdiction basis. The Company considers all available positive and negative evidence, including future reversals of temporary differences, projected future taxable income, tax planning strategies and recent financial results. Based on management’s assessment of the realizability of deferred tax assets, the Company continues to maintain a full valuation reserve on its deferred tax assets as of June 30, 2020. As of June 30, 2020 and December 31, 2019, the Company had $ 2.2 The Company’s policy is to record interest and penalties related to unrecognized tax benefits as income tax expense. For the three and six months ended June 30, 2020 and 2019, the Company had immaterial amounts related to the accrual of interest and penalties.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 10. Commitments and Contingencies Legal Matters From time to time, the Company may be a party to various litigation claims in the normal course of business. Legal fees and other costs associated with such actions are expensed as incurred. The Company assesses, in conjunction with legal counsel, the need to record a liability for litigation and contingencies. Accrual estimates are recorded when and if it is determined that such a liability for litigation and contingencies are both probable and reasonably estimable. No accruals for loss contingencies or recognition of actual losses have been recorded in any of the periods presented. In March 2019, VTT Technical Research Centre of Finland, Ltd. ("VTT") filed suit in the United States District Court for the Northern District of California alleging infringement by the Company of a patent relating to specific combinations of features set forth in U.S. Patent No. 8,558,643. The complaint sought unspecified monetary damages and injunctive relief. On January 22, 2020, the Company participated in a mediation that had been ordered by the Court. The case was not resolved at the mediation. A Markman Hearing was held on May 15, 2020 relating to a number of different disputed claim terms, and on July 9, 2020 the Court issued a Markman Order relating to those disputed claim terms. Among its determinations, the Court found that one of the disputed claim terms was indefinite, as well as any claim that had this claim term in it. On July 17, 2020, the Court issued a judgment finding all claims of U.S. Patent No. 8,558,643 invalid, based upon its Markman Order. VTT currently has until August 17, 2020 to file a Notice of Appeal of the Court's judgment. The Company has not accrued for a loss contingency relating to such matter as the potential loss is currently not probable and reasonably estimable. Indemnification The Company is a party to a variety of agreements pursuant to which it may be obligated to indemnify other parties to such agreements with respect to certain matters. Typically, these obligations arise in the context of contracts that the Company has entered into, under which the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations and covenants or terms and conditions related to such matters as the sale and/or delivery of its products, title to assets sold, certain intellectual property claims, defective products, specified environmental matters, and certain income taxes. Further, the Company’s obligations under these agreements may be limited in terms of time, amount, or the scope of its responsibility and in some instances, the Company may have recourse against third-parties for certain payments made under these agreements. It is not possible to predict the maximum potential amount of future payments under these agreements due to the conditional nature of the Company’s obligations and the unique facts and circumstances involved in each particular agreement. Historically, the Company has had no indemnification claims under these agreements.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Outbreak of Coronavirus Disease 2019 (“the COVID-19 pandemic”)	Outbreak of Coronavirus Disease 2019 (“the COVID-19 pandemic”) On March 11, 2020, the World Health Organization characterized the outbreak of the coronavirus disease known as COVID-19 as a global pandemic and recommended containment and mitigation measures. On March 13, 2020, the United States declared a national emergency concerning the outbreak, and several states and municipalities have declared public health emergencies. To combat the spread of the COVID-19 pandemic, the United States and other foreign countries in which the Company operates have imposed measures such as quarantines and “shelter-in-place” orders that are restricting business operations and travel and requiring individuals to work from home (“WFH”), which has impacted all aspects of the Company’s business as well as those of the third-parties we rely upon for our manufacturing, assembly, testing, shipping and other operations. The Company anticipates the global health crisis caused by the COVID-19 pandemic will negatively impact business activity across the globe and the Company's results of operations. The inputs into the Company’s judgments and estimates consider the economic implications of the COVID-19 pandemic, as the Company knows them, on the Company’s critical and significant accounting estimates. The extent to which the COVID-19 pandemic may impact the Company’s business will depend on future developments, which are highly uncertain and as such, the Company is not able to estimate the effects of the COVID-19 outbreak on its results of operations, financial condition, or liquidity for fiscal year 2020.
Reporting Calendar	Reporting Calendar The Company’s fiscal year begins on January 1 of the year stated and ends on December 31 of the same year. The Company reports its results on a calendar year basis.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Significant Accounting Policies	Significant Accounting Policies The Company’s significant accounting policies are disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. There had been no changes to these accounting policies except for the recently adopted accounting guidance as discussed below.
Accounting Standards Recently Adopted/Not Yet Adopted	Recently Adopted Accounting Guidance In August 2018, the Financial Accounting Standard Board (“FASB”) issued Accounting Standard Update (“ASU”) 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use-software. The adoption of this standard on January 1, 2020 did not have any impact on the Company's consolidated financial position, results of operations and cash flows. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements in Topic 820. The adoption of this standard on January 1, 2020 did not have any impact on the Company's disclosures. New Accounting Pronouncements Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. The new standard will be effective for fiscal years beginning after December 15, 2020. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial position, results of operations and cash flows. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which changes the credit loss model from an incurred loss approach to an expected loss approach. It requires the application of a current expected credit loss (“CECL”) impairment model to financial assets measured at amortized cost (including trade accounts receivable) and certain off-balance-sheet credit exposures. Under the CECL model, lifetime expected credit losses on such financial assets are measured and recognized at each reporting date based on historical, current, and forecasted information. The standard also changes the impairment model for available-for-sale debt securities, eliminating the concept of other than temporary impairment and requiring credit losses to be recorded through an allowance for credit losses. The amount of the allowance for credit losses for available-for-sale debt securities is limited to the amount by which fair value is below amortized cost. The standard is effective for interim and annual periods beginning after December 15, 2022. A modified retrospective adoption method is required, with a cumulative-effect adjustment to the opening retained earnings balance in the period of adoption. The adoption of this standard is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows.
